It would be (2,2), because of the opposite reciprocal slope of a perpendicular line.

Answer:

(2, 2)

Step-by-step explanation:

First we find the slope of the line through M and N.  The coordinates of M are (2, 3) and the coordinates of N are (-3, 2).  Using the formula for slope,

m=\frac{y_2-y_1}{x_2-x_1}=\frac{3-2}{2--3}=\frac{1}{5}

For a line to be perpendicular to a given line, the slopes would be negative reciprocals (opposite signs and the fraction is flipped).  This makes the slope of the perpendicular line -5/1.

The coordinates of point K are (3, -3).  Going down 5 units and right 1 unit would put it at (4, -8).  Going backwards, up 5 units and left 1 unit would be (2, 2).  Thus (2, 2) is the point we are looking for.

Bias refers to scenarios which might affect the ability of a statistical experiment to generalize, hence affecting the validity of research. Non-response bias occurs when majority of subjects <em>fail to respond during a survey</em>. Hence, a likely scenario is ; <em>surveys were mailed to 500 people, and 200 of the surveys were completed and </em><em>returned</em><em>.</em><em> </em>

  • Non - response bias has to do with a situation whereby a large percentage of the selected samples from a population do not respond or fail to participate in the experiment or survey.

  • If 200 surveys were returned, then 300 of the sample participants did not respond. Which means <em>60% of the sample are non-responsive</em>.

Therefore, a scenario where <em>surveys were mailed to 500 people, and 200 of the surveys were completed and </em><em>returned</em><em> </em>exemplifies a non - response bias.
